T all whom, it may concern: be made to the drawings hereto attached, in

Be it known that I, HUGO SALOMO, a suh which- 7 ject of the Emperor of Germany, residing at Figure 1 is a plan looking down from the 50 No. 148 Bourke Street west,in the cityof Meltop, and Fig. 2 an end elevation, of this rebourne and British colony of Victoria, engitary pump and blower. Fig. 3 is a horizontal neer,have invented an Improved Rotary Pump section on the center line a a, Fig. 2, but showaud Blower, of which the following is a speciing the disks by a top view in the act of workfit ation. ing together. Fig. 4 is a side elevation of the This invention has been designed, princimachine with one of the disks and its casing pally, for use as a rotary pump, although it taken off, and with part of the wedge shaped may also be used asarotary blower. I intend piece between the disks broken away in orto call it the Hydranlantfii der to show the central section of the inlet- It consists ofa novel combination of novel bend. Fig. 5 shows a face view of one disk 6C, contrivances. These novel contrivances conwithin its casing.

The pumping-disks made, preferably. of brass, and A A are the 6 are each made with a conical face and a re radial ribs or teeth projecting from their faces,

cessed back. On the face of each are radial one side of such ribs or teeth 0 being shaped ribs or teeth extending from the center to the similar to the teeth of a bcvel-wheel, so as to periphery, the faces of which ribs are wholly allow them to gear with and work quite close on the one plane. They each have a stop he. to each other, as shown in Fig. 3.- Thesedisks 7o hind each rib, and they are each carried by are keyed upon their respective spindles A,

The two checks or casings one of which is long enough to allow of the flyare dished to receive the pumping-disks, and wheel A and pulley A" being secured thereon, are so made as that their lips or flanges meet so as to enable it to be driven either by manfor about one-half of their circumference and ual power or by belt from any other moving 7 5 then diverge from one another,so as to leave a machinery.

These 5 tion-chambers. These cheeks are also so conchecks are secured to the wedge-shaped piece structed as to provide a suitable discharge- 0 by the bolts B and to each other by the opening. The wedge-shaped piece is made to bolts B suitable flanges, B being provided accurately fit the wedge-shaped space left beupon them for that purpose. 8 5 tween the two halves of the two checks. The By reference to Fig. 5 it will be noticed that 40 supply-pipe is made in it, and leads to aquadeach of the cheeks B has one-half of the outrant-shaped opening out quite through it belet branch B and a vacuum-recess, B formed tween the two disks, so as to allow the supply in them, as shown. The wedgeshaped piece to pass from such opening to the spaces be- 0 is faced true upon its surfaces to allow of the 0 tween the ribs or teeth of the disks on both disks on either side working against it, and in 4 5 sides of it. the upper portion of it is a quadrant-shaped In order, however, that this invention may opening, 0, quite through it, into which the be more clearly understood, reference will now inlet or suction branch 0 leads. The lower portion of said wedge-shaped piece beneath the chamber 0 is hollow, and forms flanges to receive the bolts B", which flanges are cast or formed upon the lower or standard part, 0, of the wedge-shaped piece.

0 is a foot-plate, in which are the holes G, to receive the holding-down bolts for affixing the machine to its frame or foundation.

"A are small projecting snugs upon the face of each conical disk near its outer edge, between which snugs and the ribs or teeth of the one disk the ribs or teeth onthe opposite disk gear, and so prevent theirstriking against one described,,of the two-part casing B, provided another when the machine is reversed.

The arrows D show the course of the air or liquid passing through the machine.

The mode of operation is as follows: Theinlet branch 0 is connected to the suction-pipe. One of the disks is driven by machinery, or otherwise, and those ribs or teeth which are beyond the point of the wedge-shaped piece 0 gear with those on the opposite disk, and so a rotary motion is imparted to it also. This rotary motion produces a vacuum in the chamher G, into which the air or liquid finds ingress, and from whence it passes through the quadrant-shaped opening (3 into the spaces between the radial ribs or teeth A, which confine and carry it down between them and the lower faces of the wedge-shaped piece 0. Immediately it passes the point of this wedgeshaped piece the ribs or teeth A begin and gradually increase the depth of'theirgear with each other, thereby ejecting the whole of the air or liquid into the outlet or delivery branch B. It will be observed that as the conical disks A are recessed at their backs the air or liquid finds entrance thereto, and so forms a cushion, which materially assists in causing the said disks to rotate freely on their workingfaces by preventing any undue friction.

-Having now particularly described and explained the nature of my said invention and in what manner the sameis to be performed, I declare that what I claim is- 1. The herein-described rotary pump, comprising the two-part casing B, each part having one'half of the outlet branch and of an air-chamber, B formed therewith, and constructed to form awedge-shaped space between them when assembled, the wedge-shaped piece 0, having inlet branch O and sector-shaped inlet-ports 0 formed therewith, and conical winged or ribbed disks arranged to rotate on opposite sides of the wedge-shaped piece 0, substantially as described, for the purpose specified. a

2. The combination, substantially as herein with tubular shaft bearings and interior recesses, B, said parts being constructed to form a wedge'shaped space between them when assembled, the wedge-shaped piece 0, having inlet branch formed thereon, and provided with sector-shaped inlet-ports 0 arranged in said wedge-shaped space and dividing a portion of the interior of the casinginto twochambers of like cross-sectional area,with the conical winged or ribbed disks A, having one side or face, 0, constructed in the form of a bevel gear-tooth and arranged to rotate on opposite sides of the wedge-shaped piece 0, for the purpose specified.

3. The combination of the two-part casing B, having outlet branch B and interior" reccsses, B, and the wedge-shaped piece 0, having inlet-branch O chamber or passage 0, and sector-shaped inlet-ports G with the conical revoluble disks A, having ribs or wings A, the face 0 of which has the form of a beveled geartooth,and provided with projecting snugs A said disks being arranged to rotate on opposite sides of the wedge-shaped piece 0, said parts being constructed, arranged, and operating substantially as described, for the purpose specified.
